HUDGER BBUNEAU, OF VJO'ONSOCKET, RHODE ISLAND.

PICKER ROD.

Application filed May 20,

To all 007mm if; may concern.'

Be it known that I, I-IUDGER BnUNnAU, a citizen of the United States,residing at lVoonsocket, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in PickerRods, of which the following is a specification.

My invention relates to picker rods or spindles for looms, andparticularly to those ot the detachable type.

Heretoit'ore it has been customary to retain such rods by a set screw.r1`he violent vibrations due to the lmovements of the lay and theshuttles loosed the screw and released the rod with resultant smashing.

The essential objects of my invention are to overcome the accidentalrelease of the rod.; to facilitate lubrication of the same; and toattain these ends in a simple, inexpensive, and adaptable structure.

To the above ends essentially my invention consists in such parts and insuch cornbinations of parts as fall within the scope of the appendedclaim.

In the accompanying drawings which term a part of this specification-Figures 1 and 2 are a plan view and a rear elevation respectively of theshuttle box upon which my device is mounted, and

Figure 8, a section on line 33 of Figure 1.

Like reference characters indicate like parts throughout 'the views.

In the embodiment ot my invention here in illustrated 5 is a fragmentaryshowing of the portion of the lay adjacent the shuttle box 6 whose rearwall 7 constitutes the guide for the picker 9 actuated by the pickerstick 10 to drive the shuttle 11.

Near the inner end of the rear wall 7 ot the box is a lug 15 providedwith a hole 16. Fixed to the outer end of the box is a tube 18 having aclosed outer end 19 and disposed in longitudinal alignment with the lug.In this instance the tube is fixed to the end wall 21 of the shuttle boxby an attaching screw in a horizontal bracket or arm 22 integral withthe tube 18. Near the open end of the tube is slidably mounted a bearingmember 24 provided with a central tapering bearing or cavity 26, andenclosing the inner 1924. Serial No. 714,560.

end oit a helical spring 28 whose outer end abuts against the closed end19 of the tubo.

Fitted in the hole 16 of the lug 15 is bearing member 8O comprising alshank 31 and a squared head 32. The latter abuts against one face of thelug and has a conical cavity 34 extending to a central longitudinal boreThe shank 30 extends through and beyond the lug and is provided with anexternal thread 36. An oil cup 38 has a bowl 39 and a neck 40, thelatter being provided with a central oil passage 41. At its end thepassage is enlarged to form a cavity 42 in which is a thread 43 engagingthe thread 86 whereby the end 'tace of the neck is tightened against theface of the lug 15 and the screw31 is firmly held in the lug.

The picker rod 45 is tubular and provided with conical ends 46 and 47and contains a core or wick 48 of absorbent material extendingthroughout its length. A hole 50 in the wall ot the rod near its outerend is for the emission of the lubricating oil extracted and distributedupon the exterior of the rod by the reciprocation of the picker. The end46 of the rod is seated in the cavity 26 of the cap or slide 24, whileits opposite end 47 is seated in the cavity or bearing 34 of the ixedmember 31. The wick 48 is supplied with lubricant from the bowl throughthe oil passage 41 and 35.

The rod may be manually removed, when necessary, by pushing itlengthwise against the member 24 which yields sutliciently to permit theopposite end of the rod to be withdrawn and moved laterally of themein-- ber 3l, whereupon the end 46 will. be ejected by the action ofthe spring. l/ilhen the rod is in normal position the pressure exertedby spring 28 insures such a firm seating ot' its conical ends in theirrespective bearings as to insure retention of the rod despite anyvibration of the loom.

The combination in the element 31 oi the functions ot a seat for the rd, a retaining element tor the oil cup, a conductor ot the lubricant,and a binder to the supporting lug, affords a. simple, strong, easilyassent bled, and simple construction.

I claim In a loom, a shuttle box, a bearing member yieldingly supportedby the b x, i lug on the loo box provided with i hole, a. bearing memberin alingment With the first hearing inein- 1oer comprising a sha-iik inthe hole provided with a central longitudinal passage and with 'athreadand a. head engaging the lii'g provided with :i Cavity oommuneaing withthe passage, an oil cup comprising a. bowl and a neck engaging the lugprovided With a pasengaging the first hearing member :ind having itsopposite end seated iii the cavity.

In testimony whereof I have zifixed my signature.

HUDGER BRUNEAU.
